Seat material affects chemical resistance, leak integrity, and longevity in welding gas regulators. PTFE Teflon® is common for its durability and compatibility with many gases, while PCTFE (Kel-F®) is used for demanding applications. For instance, the Harris 9200-200-350 uses PTFE Teflon® for reliable sealing, while the Harris HP8700-4500-347 features a PCTFE seat for high-pressure air. With several seat materials available, you can choose the best one for your specific gas and application.
